Biomarker Data in Melanoma Presented at ASCO 2018 Are Largely Extensions of Previous Studies Rather Than New Discoveries

Dr Sanjiv Agarwala argues that much of the biomarker data in melanoma presented at ASCO 2018 are around the value of PD-L1 testing; however, even PD-L1–negative melanoma patients seem to respond to anti–PD-1 therapy, although some studies suggest PD-L1–negative patients may be better candidates for combination immunotherapy.
